Nordgens are expensive young players that get skill points fast. Their growth gives you chance to use them for few seasons. Look at my previous post. This GK is nordgen. When I bought him last season, he had 5 stars on level 9 and rating 64. Now he has 6* on level 11 and very high defensive rating. He'll play for my club for next 3 seasons.

No one can choose or change server. Sometimes even invitation doesn't help.
